4700 Refrigerated Sampler Service Guide
Section 1 Introduction and General Guidelines
1-9
1.4.3 Cleaning the Pump
Rollers
Debris should be removed from the rollers and guides to keep the
pump operating efficiently and to extend tubing life. Remove
loose debris from the pump rollers and guides with a stiff
nylon-bristle brush. If debris has built up and cannot be removed
with the brush, scrape the rollers or guides with a plastic or
wooden tool to loosen the debris.
CAUTION
Do not use a metal tool. This might damage the plastic rollers
and guides.
1.4.4 Cleaning the Pump
Housing
Remove loose debris from the pump housing with a stiff
nylon-bristle brush. If needed, flush debris from the housing with
water. Do not spray with pressure. This might force water
through the seals and bushings and damage internal compo-
nents.
1.4.5 Cleaning or Replacing
Wetted Parts
For general cleaning, you can wash the strainer and sample
bottles with a brush and soapy water, then rinse with clean
water. You can clean the liquid path through the wetted parts
(Figure 1-4) by placing the strainer in a cleaning solution and
pumping it through the delivery system. Next, place the strainer
in clean water and pump it through the delivery system to rinse
it. If these items are severely contaminated, replace them.
Example: Resetting the Pump Tube Alarm
1.
From the Main Menu screen select CONFIGURE.
2.
Step through the Configure options until you see
the TUBING LIFE display. Press Enter
3.
The sampler briefly displays the current pump
count information. Line one lists the pump counts
since the last reset. Line two lists the current alarm
setting. The screen will advance automatically.
4.
To reset the counter to zero, select YES. Always
reset the counter after replacing a pump tube.
Select NO when merely checking the current
count.
5.
You can modify the pump tube alarm setting to
tailor it to your needs. The factory default setting is
1,000,000 pump counts. However you may
experience tube wear more or less frequently.
Change the pump-count alarm setting by typing the
first two digits of the new setting. The sampler
accepts entries between 1 and 99. For example, to
increase the count to 1,500,000, enter 15.
A pump tube alarm should be set to notify you when
the pump tube should be replaced. A pump tube
should be replaced when it begins to show signs of
wear, long before the tube wall fails. For more
information, refer to section 1.4.1.
